The answer is definately A
Answer:
b = (d-c)/a
Step-by-step explanation:
ab + c = d
We want to solve for b, so we need to get b alone
Subtract c from each side
ab+c-c = d-c
ab = (d-c)
Divide each side by a
ab/a = (d-c)/a
b = (d-c)/a
Given:
Speed = 6 miles per second
If the Saturn revolves 6 miles in 1 second then the speed is:

So speed in minutes is 360 miles per min.
In 3 minutes traveling distance is:
Answer:

Step-by-step explanation:
If two lines are perpendicular, they create 4 90° angles. Meaning, in this case, that m<DBC = 90 and m<DBA = 90.
We're given that m<DBE = 2x - 1 and that m<CBE = 5x - 42.
The sum of angles DBE and CBE = m<DBC = 90°
We can add the two angles and set it equal to 90 to find x

Answer:
x=15
Step-by-step explanation:
Substitute the values to check your answer...
(x²-11x)=60
(15²-11*15) =60.
